Application of Big Data Analysis in Path Planning of Intelligent Picking Robot

Abstract

In order to solve the problem of autonomous movement of intelligent picking robot, a method for big data analysis is proposed. The data collected by laser ranging sensor, CCD camera and electronic compass are analyzed to determine the current robot position and heading. The walking route for the robot is preset of the orchard. The sign for the digital tube is installed, so the coordinates for the sign are known. Electronic compass is used to determine the heading angle of robot. The CCD camera captures the sign image, and adopts the methods of image graying, image segmentation, image corrosion and image thinning to extract the digital tube image data on the sign. Fuzzy control method is used to identify digital tube numbers on the ground sign, and CCD camera scans whether there are obstacles in front of the road at the same time. The laser ranging sensor completes two tasks: ① detecting the sign distance and direction angle of the distance, and calculating the current position and heading angle of the robot through the coordinates of the sign; (2) detect the distance from obstacles, and start the obstacle avoidance system when it is less than 1m. The path planning system of picking robot based on big data analysis relies on a variety of sensors, and has a strong ability to perceive orchard environment, and it has high ability of path planning.

Organization and Planning of Garden and Park Facilities Taking Into Account Modern Trends

“…In the history of the country's modern decorative nurseries, there are many achievements and unsolved problems [3, 6,]. The positive aspects of its development include, first of all, the formation of an extensive network of nurseries under private ownership [5,9,10], a significant expansion of the assortment of tree cultivars and the assortment of products at state and communal enterprises [5], the mastery of new technologies for propagation and cultivation of planting material , in particular, an increase in the specific weight of container culture [8,9], the start of production of accompanying materials (universal and specialized substrates, containers, fertilizers, etc.) and, in general, an increase in the specific weight of domestic products on the market of Ukraine and abroad [2].…”

“…Planting material is divided into basic, additional and limited assortment according to the sum of characteristics (stability and longevity of the species in the given natural conditions and conditions of a specific object) and according to the decorative qualities of the species grown for landscaping [ 10].…”

Application of Laser Ranging in Path Planning of Mobile Medical Robot

“…the actual planning and control, the reflective behavior, reactive behavior and deliberative behavior of mobile robot are combined. Due to the consumption of battery power in the process of robot movement, the actual voltage will be less than the rated voltage of battery, resulting in the actual movement speed of robot will be smaller than the theoretical value [14]. According to the sensing area, the laser rangefinder selects the angle range that should be set, and selects the corresponding sector rolling planning window.…”
